one of our remote site lost communication at mid-night, but there was no indication on Hive Cloud however when i collect router logs I saw log created at same time when we face outage. but the log say something about the "operation too slow". now what could be the reason behind loosing Comms to our remote location. we are using a 4G LTE cellular link at our remote locations. is there anyway we can tweak the link parameters for low latency circuits so link stay stable and connected and without any packet drops?
